SPECFXGATIGN forming part of Letters Patent No. 697,384, dated April 8,1902. Application filed May 1, 1901. Serial No. 58,377. (No model.)

To all whom, t may concern:

Beit known that I, JOHN W. PAUL, a citizen of the United States,residing at Kittanning, in the county of Armstrong and State ofPennsylvania, have invented new and useful Improvements in Type-Writers,of which the following is a specification.

My invention relates to improvements in type-writers, and pertains to amachine of the visible-writing type and wherein the typebars arearranged in a substantially horizontal basket. v

The primary object of this invention is to provide a simple arrangementand construction of the type-bar action wherebya straight, easy, andpractically uniform touch is effected.

A further object of my invention is to so construct the shiftingmechanism for the vertically-movable type-bar basket that a quickactingand easy-touch shift is provided.

A further object of this invention relates to the construction andarrangement of the several parts of the mechanism hereinafter shown anddescribed whereby an improved machine of the visible-writin g type isproduced.

In the accompanying drawings, Figure l is a central longitudinalvertical sectional view of the machine embodying my invention, thecarriage and the carriage mechanism being omitted, as that forms nopartof my present invention. Fig. 2 is a detached perspective view ofthe type-bar basket with only a portion of the type-bars shown inposition therein to more clearly disclose the specific construction ofthe basket and the arrangement of the type-bars. Fig. 3 is a top planview on line 3 3 of Fig. l, the type-basket being omitted to disclosethe type-basket-shifting mechanism and the universal-frame mechanism foreffecting the feed of `the carriage. Fig. 4 is a sectional view on theline e 4 of Fig. 3 and looking in the direction indicated by arrow. Fig.5 is a sectional view on the line 5 5 of Fig. 3 and looking in .thedirection indicated by arrow. Fig. G is a central vertical longi*tudinal sectional view through the type-bar basket, the type-bars andkey-levers being 5o omitted.

In a machine of the character herein shown there is essentially ahorizontal frame A, hav- Y ing at one end the vertically-arrangedstandard B, upon .which is supported a suitable carriage, and situatedwithin the horizontal frame A below the carriage is a verticallyshiftingtype-bar basket O, in which are arranged the type-bars and thekey-levers.

The combined type-bar and key-lever bas-V Referring now to theconstruction and ar- `rangement of the type-bar basket, the typebars,and the key-levers, it will be noticed that one end of the type-barbasket consists of a block G, having grooves ZJ in its upper and lowersides, and located within these grooves are the type-bar division-platesc. Located between these division-plates are the type-bars H, whichare'pivotally supported at their inner ends through the medium of asuitable rod d and carrying at their outer ends the type-bar block c,which contains the caps and small letters, as is well understood bythose skilled in the art.

Projecting downward fromthe under side of the basket O at a pointintermediate its ends is a vertically-arranged plate I, having in itsunder side a plurality of slots f, thus constituting a comb. The innerends of the v L-shaped key-levers J rest in these slots f,

andthe outer portions of the key-levers are guided and moved invertically-arran ged slots g', formed in a downwardly-projecting plateK, located at the opposite or outer end of the basket to that at whichthe .type-bars H are pivoted.

In a type-writer ofthe character here shown it is necessary that thetype-bars be arranged in the arc of a circle and radially in respectthereto, and it is the primary object of my present invention to soconstruct and arrange the key-levers and the intermediate mechan-j /IOOism between the key-levers and the typebars that although the type-barstravel in radii to the arc of a circle in which they are arranged, yetthe key-levers will move in a vertical plane. This result isaccomplished through the medium of the intermediate essentially L-shapedlevers M, carrying at their inner ends suitable sockets t', adapted toreceive and act upon the pivotal ends of the type-bars in a manner whichis well known to those skilled in the art and need not be specificallydescribed. At the intersection of the vertical portion Z of the L-shapedlevers M a pivotal rod or other suitable pivotal support m passes forthe purpose of forming a pivotal connection for the said L-shapedlevers. The key-levers J are located at one side of the lower ends ofthe vertical portions Z of the levers M, and the key-levers are providedwith laterally-projecting pins n, which project into suitable cam slotsq, formed in the lowerends of the said vertical portions of the L'shapedlevers M. By means of this construction when a key-lever is depressedthe pin n thereof will by its engagement with the cam-slot q of theintermediate lever M cause its inner free end to move upward, and thisupward movement will cause the type-bar H to be thrown up and againstthe printing-roller, as will be readily understood.

As before stated,the type-bars are arranged in the arc of a circle, andhence the intermediate levers M must be arranged to correspond with thetype-bars. They are likewise arranged in the arc of a circle. Thekey-levers are arranged in a common horizontal plane, and owing to thisarrangement of the key-levers it will be at once appreciated that thelength of the vertical portionsl of the levers M will vary according toits location in order to reach 'the key-levers. On account of thisconstruction the L-shaped intermediate levers M lying at or near thecenter of the type-bar basket have their vertical portions Zshort; butowing to the circular arrangement of the type-bars and theseintermediate levers M it is necessary that the vertical portions Zof thelevers M situated at opposite ends thereof be longer and be deected at asuitable point-for instance, at the point lr--to cause them to extend ina vertical plane.

Owing to the fact that the vertical portions of the levers M are ofvarying lengths and the desirability of having a uniform downwardmovement to the key-levers the inclination of the cam-slots q in thevertical portions of the intermediate levers M must of necessity vary.For instance, by referring to Fig. 2 it will be seen that the said slotq' in the central lever M is but slightly inclined, while the slots q inthe end intermediate levers M are at a considerable angle. This is sofor the reason that the longer vertical portions of the intermediatelevers M must travel farther than the short portions of some of theother levers M in order to give the inner free ends the key-levers andassisting in the quick return to their normal positions I provide aspring for each of the key-levers. As here shown the form of springconsists of a doubled wire N, which passes through an opening s in theinner end of the key-lever, the ends of the said Wire passing throughthe openings t, formed inthe comb or plate I, the tension of the saidspring serving to lift the outer free ends of the key-levers and to holdthem in their normal positions.

The means for shifting the basket vertically for the purpose of writingin caps consists of a transversely-arranged pivotal bar 2, which hasrigidly secured thereto an outwardly-projecting arm 3. The free end ofthis arm 3 engages the under side of a suitable shoe 4, which isattached to the block G and extends downward and inward and has itsopposite end connected with the downwardly-projecting comb or plate Iand serves the additional function of assisting in supporting the plate.Rigidly connected to opposite ends of the said pivotal rod 2 and eX-tending forward are the arms 5, which are rigidly connected with asuitable counterweight 6. This counterweight 6 is here shown in the formof a flat sheet or plate of lead or similar material and serves, throughthe me dium of the arm 3, which is in. engagement with the inner freeend of the vertically-movable type-bar basket C, to lighten the heft ofthe inner end of the said type-bar basket.

Preferably I provide two shift-keys 7, the same being located atopposite sides of the machine, though, if desired, but one shift-key maybe used. The inner ends of these shiftkeys 7 are pivotally connected tothe horizontal frame A in any suitable manner at the points S and areintermediately connected with the outer ends of the arms 5 through themedium of suitable wire or other links 9.

When t-he typefbar basket is in position, its inner end, being inengagement with the inner free end of the arm 3, lifts the outer freeends of the arms 5 and in Vturn the counterweight (5, which is rigidlyconnected therewith, and through the medium of the links 9 also liftsthe shift-keys 7 to their normal positions. A downward pressure uponeither one of the shift-keys 7 will canse a corresponding downwardmovement of the counterweight and the free ends of the arms 5, and thisin turn will lift the inner free 'end of the arm 3 and cause the liftingof the inner free end of the vertically-shifting type-bar basket.

ICO

For the purpose of enabling the'type-bar basket to be locked in itsshifted position when writing a word or asentence in caps I provide anysuitable form of locking lever or latch. As here shown I provide a lever10, intermediately pivoted to the frame A, which lhas its lower endadapted to engage the upper edge of the-free end of one of thevarms 5ofthe shifting frame, whereby when the said lever is moved inthedirection indicated by arrow in Fig. 4 it will cause a downward movementofthe outer end of the shifting frame and 'ai corresponding upwardmovement of the inner end of the shifting frame, and' thus servetobasket in the position tov lock the type-bar write in caps.

-The carriage-feed mechanism involves a universal frame, as is usual-inall type-writ` ers,fand thisuniversal frame as here shown is comprisedof a pivotal rod'1`1, located at one end of the frame and below thecarriage,v

outwardly-extending armsL 12, which are rigidly connected with vthe saidrod 11, and a straight horizontally-arrangedYbar 14, which extendsdirectly under the key-levers J and adapted to be engaged thereby whenthe keylevers 'are 'depressed' foi` the' purpose of oscil-v lating therod 11, to which is rigidly connected the dog-supporting Iframe v15.From this descriptionit will 'be noticed that the uni! versalfeeding-'frame is of'a rectangular -character and presents aperfectly-horizontal surface to the under side ofthe key-levers J andthat there is -no'lateral-'or grinding action between the key-levers andthe universal frame in the movement of the type-action of the machine.

'The'spa'ce mechanismhere shown consists of a U-shaped frame 16, whichhas its ends` pivotally connected at the points 17 to suit-V able ears18, which projectfrom the frame A. The means whereby the movement of thespace-bar16'is transferred to the universal feed-frame consistsV of anarm'l20`, which has its inner end 2l, as shown in Fig. 3,'looselypivoted upon the rod 2 and vmovablelinde pendentthereon. This bar'20curves upward and hasits outer end loosely inserted into an opening 22of a depending arm 23, extending" be regulated relatively'to themovement ofV the key-levers, 'as some'operatorsdesire'an earlierfeedof'the carriage in respect to the movement of the key-levers and thetype-bar than others. This is `accomplished through the medium-of abearing strip or plate 25,' which has one endf26'pivotally connected toythe said arm 20andits opposite end 26"con' structed to beverticallyadjustable in respect to thesaid arm or lever 20through the mediumv of aslot and screw, as here shown at26;

The vertical movement of this bearingstrip orplate 25 will cause acorrespondingmovement through the iengagement therewith of the barpli,constituting the inner end of the universal feeding-frame, andthu'scause acorresponding adj ustment'of the feed-dogs in relation to thecarriage-rack.' Thisv vertical movement of the rod 14 willcause it to benearer to or farther from the key-levers, thus regulatingthe period atwhich the feed of the carriage occurs relative to the Vmovement of thetype-bars and key-levers.

I do not limit'myself' to thespecilic construction and specificarrangement of the parts herein enumerated, as these may be varied'bythose skilled in the art withoutmaterially. affecting the spirit orscope of myinvention. f
